IMPROVEMENT IN MAN'URE-SPREADERS.

Specification forming part of Letters Patent-No. 1l,557, dated August 22, 1854.

To all whom it may concern! -Be it known that I, ELBRIDGE MARSHALL of Clinton, in the countyot' Hunterdon and State of .New Jersey, haveinvented a new and usefullmprovement iu-GuanmSowers and Ma- I pure-Spreaders; and I do hereby declare that the following is a full, clear, and exact descrip- ;,ti'on of the same, reference being had to'the accompanying drawings, forming part of this specification, in which- Figure 1 is a plan or top view of a guanosowing machine with my improvements. Fig. 2 is a vertical section of the same through the line a, a in Figs. 1 and 2, and Fig. 3 is a vertical transverse section of the samethrough the This invention relates to a new and useful improvement in machines for sowing guano and spreading manure, whereby. all possibility of the machine becoming clogged is avoided anda regular and-perfect distribution of the substance being sown effected.

The nature of myiinvention consists in the employment of a horizontal vibrating brush which is arranged directly under the feed-cylinder of a guano-spreader and caused to act upon the same and brush out the guano which may collect in the grooves of said feed-cylim der. By thus employing avibrating brush the feed-cylinder can always be kept 'free from clogging and the guanowill be-spread evenly and perfectly over the whole of the soil.

To enable others skilled in'the ,art to make and use my invention, I will proceed to describe its construction and operation.

A'B represent the frame of 'the machine,

;=',made.of wood-,-and of the form shown in the drawings or otherwise.

- 0 represents the hopper.

.' ".I) is, the feed-cylinder. E are blades arranged round the periphery of the same, as

'. shown.. F are the grooves formed between said blades. This cylinder is caused to revolve by means of a band,.G, leading from a pulley, 0,

on its shaft to a pulley on the shaft of the propelling-wheels H II, as shown in Figs. 1 and 2. The speed of this cylinder can be changed, as-desired, by shifting the beltfrom the pulleys c (I to those cf or gh.

I is a blade, which acts in concert with the blades on the cylinder, and serves, with said blades, to pulveri'ze the manure or other substance before it is discharged upon the soil. ThebladeI isinade adjustable by theset-screws j j, and can be set so as to cut fine or-coarse, as desired, as may be evident from the drawngs. y I J is the vibrating brush for preventing the cylinder clogging Its arrangement will be clearly seen bylooking at the drawings. 1t

inoves back and forth under the cylinder in he guides It 16, attached to the frame, and in its movement strikes the manure adhering to the cylinder or sticking in the grooves between the blades and causes it to separate and fall upon the soil. The machinewould be of very little utility were it not fort-his brush, for in inany instances, when the manure is damp, it would adhere to and pass r'ound continuously with the cylinder, and consequently a greater portion of the soil wouldbe .left bare or unim-' proved in passing over-it.

" K is a cam secured fast on the shaft of the propelling-wheels, and L is a bent lever or arm connecting the said cam to the vibrating brush in the manner shown in Figs. 1, 2, and 3,; This le'veror arm turns on afulcrum at l,:and

. when'operated upon by the cam, and as it is moved from the position shown in.Fig. 1 to the position shown in Fig. 2, and vice versa, causes the brush to vibrate or move back and forth,

as will be evident from the drawings.

What I claim as my invention, andkl'esire to I secure by Letters Patent, is-- The employment of the-vibratingbrush; substantiallyas and for the purposes'set forth. ELBRIDGE MARSHALL.
